First, I am looking for my grandfather's father's name.My grandfather Adolf Eichstaedt entered the US from Bremen, Germany in 1907. He had a brother Emil and sisters Wanda and Lydia also originating from Germany and all settling in Chicago. Another brother Rudolf remained in Germany.I do not know the town in Germany where the family may have lived. Second, I am looking for two living cousins in the US whose maiden name is Eichstaedt. They both were born in the early 1940s. One is Joan who may be using the name Edwards from a previous marriage with a last known address in Illinois.The other is Mary who may be using the name Unbricht.
